Abstract

Изобретение относится к области обработки цифровых изображений и может быть использовано для решения задач подавления шума цифровых изображений, полученных с помощью высокоэнергетического излучения, в том числе рентгеновского. Более конкретно, данное изобретение предназначено для подавления шума цифровых рентгенограмм. Задача настоящего изобретения - разработка способа подавления шума цифровых рентгенограмм с расширенной функциональностью, в частности с возможностью уменьшения уровня остаточного шума и артефактов в виде разрывов непрерывности, направленных вдоль локальной ориентации границ объектов в текстурированных областях изображений; с возможностью уменьшения уровня остаточного низкочастотного шума; а также исключением пересглаживания (чрезмерной фильтрации) мелких деталей. Технический результат - повышение качества обработки цифровых рентгенограмм.The invention relates to the field of digital image processing and can be used to solve the problems of suppressing the noise of digital images obtained using high-energy radiation, including X-rays. More specifically, the present invention is intended to suppress noise in digital radiographs. The objective of the present invention is to develop a method for suppressing noise in digital radiographs with extended functionality, in particular, with the ability to reduce the level of residual noise and artifacts in the form of discontinuities directed along the local orientation of object boundaries in textured image regions; with the ability to reduce the level of residual low-frequency noise; as well as the elimination of oversmoothing (excessive filtration) of small details. EFFECT: improved quality of digital radiographs processing.
